More lycoris continue to open every day. Their flowering season coincides quite close with the hurricane season. These amazing amaryllids pop up almost overnight, sans foliage. If you’re curious to take a deep dive into the genus, check out our lycoris study gallery
Lycoris chinensis is a spring-leaf species from China.
Lycoris longituba is the tallest species with the largest flower. It is typically white, but can come in yellow and pink. Anything other than white is quite rare.
Lycoris x incarnata ‘Peppermint’ is a hybrid of Lycoris longituba x Lycoris sprengeri. This is an exceptional plant as you can see below.
Lycoris x longitosea is a hybrid of Lycoris x incarnata and Lycoris radiata. This is an extraordinarily rare hybrid.
Lycoris x sprengensis is a group of hybrids between Lycoris sprengeri and Lycoris chinensis, both spring-leaf species. This is an old, but impossible to find hybrid from the late Sam Caldwell.
Lycoris ‘Summer Moon’ is a yet to be introduced hybrid from lycoris breeder Phil Adams of the same cross above.
Lycoris ‘Matsuribune’ is a hybrid from the late Mr. Komoriya of Japan, who crossed Lycoris sanguinea and Lycoris sprengeri. We can’t really grow the orange flowered L. sanguinea due to our summer heat, but this hybrid excels.
Lycoris ‘Yoimachi’ is another cross with the same parentage above, also from the late Mr. Komoriya.
Lycoris ‘Gennen’ is an exceptional Komoriya hybrid, resulting from a cross of Lycoris radiata x Lycoris chinensis.
The spring garden at JLBG has a number of phallic moments if you’re lucky enough to catch them. Here are a few of our favorites. Below is a color echo we created, using Pig’s Butt Arum (Helicodiceros muscivorus) and Salvia x nemorosa. We’re sure you’ll want to recommend this combination for everyone in your HOA.
It’s cousin, Dracunculus vulgaris has also been putting on a show recently. Although the typical red maroon-flowered forms won’t flower for another week or two, the rare white-flowered forms, native only to a small region of Crete, are stunning now.
Dracunculus ‘Spring Bling’ is an Alan Galloway hybrid with a creamy spathe, with a blush purple flush, and black spadix.
Below is another of Alan’s crosses that we’ve named Dracunculus ‘White Tux’ with a stunning white spathe and contrasting black spadix.
Dracunculus ‘White Rhino’ is the most vigorous of all the white-flowered clones we grow. This is yet another Alan Galloway selection, rescued from Alan’s garden, after he passed away at the all too early age of 60 years.
A few years before Alan passed, we were chatting one day about crazy plant breeding projects, and Alan mentioned that he was going to try crossing Arum with Helicodiceros. I told him I suspected he might have better luck crossing Helicodiceros with Dracunculus, since they intuitively seemed to be a better match. He mentioned that both would be in flower in his garden shortly, so he’d be on the case.
Thanks to Alan’s meticulous breeding work, the cross was successful, and three seed eventually germinated. For several years, the foliage of the seedlings looked so similar to Helicodicerous, we both assumed that it was not actually a hybrid. Finally, the year prior to his death, the first of the three seedlings finally flowered, and indeed, he had been successful in creating a bi-generic hybrid, x Helicunculus gallowayii. The foliage, spadix surface appearance, and the flower orientation resembles Helicodiceros. The spathe and spadix are both much longer, the color is more intense and the spathe much more wavy and canoe-shaped, thanks to the Dracunculus parent.
All three seedlings were rescued, but so far, only the original clone has flowered. This week, as it opened, we are once again reminded of Alan’s amazing contributions to the horticultural world, with the flowering of his namesake.
Looking great in the garden now is the false red agave, Beschorneria. Beschorneria is a small, little-known genus of only 8 species of plants in the Asparagaceae family–first cousin to the better known genus, Agave. Beschornerias are native from Northern Mexico, south to Honduras. Through the years, we’ve grown 7 of the 8 species, having not bothered to try B. wrightii, due to it’s tropical origin.
The only species that has proven reliable and evergreen here is Beschorneria septentrionalis–a species introduced by the former Yucca Do Nursery from their collections in Northern Mexico.
Several years ago, we were given seed of hybrids of B. septentrionalis x B. yuccoides ssp. dekosteriana. Most of the hybrid plants died because they inherited too many genes from the more tender B. yuccoides, but two plants still remain. Below is one we named Beschorneria ‘Fire Towers’, which appears close to B. septentrionalis in appearance, but perhaps with a bit more vigor.
We always get excited when the Osmunda regalis fronds begin to unfurl in the bog garden at JLBG. Here are some images from this week, showing the new fronds. The rosy emerging growth is the sterile part of the fern frond, while the green growth at the top is the fertile part, which will produce the spores (fern seed). Hardiness Zone 3a-9a.
Below is another clump nearby, that emerges about a week earlier, and as such, is further along in opening.
Below is our hybrid, Osmunda x japalis ‘King Kong’, a cross between the American native Osmunda regalis and the Japanese native, Osmunda japonica. Unlike the 4-5′ tall Osmunda regalis, Osmunda japonica is much smaller (to 3′ tall), emerges 1-2 weeks later, and has dimorphic fronds—the spores are on different stalks than the foliage. Our hybrid has dimorphic fronds like the O. japonica parent, emerges later, but is much larger to 7′ tall.
We continue to be impressed with the continuing parade of new selections of sterile lenten roses, in particular, the clones of Helleborus x iburgensis. These fascinating hybrids that originated at RD plants in England, are crosses of Helleborus x ballardiae (niger x lividus) x Helleborus x hybridus. In other words, these hybrids have up to 5-7 different species in each.
Because two of the parents, Helleborus niger and Helleborus lividus, both have outfacing flowers, the flowers on the Iburgensis hybrids all carry that trait. Additionally, most every lenten rose cross with Helleborus niger is effectively sterile. Interestingly, Helleborus niger is the most cold hardy of all lenten rose species, while Helleborus lividus is the least cold hardy, but the most heat tolerant.
Below are a series of photos from the gardens here over the last few weeks of some of the clones we have tried. We find these an exceptional group, many with pink to cream variegation, that should be much more widely grown. Hardiness is Zone 5a-8b, at least.
Flowering recently in our heated greenhouse was the little-known Paramongaia weberbaureri. This fascinating bulb, native to Coastal Chile at 10,000′ elevation, is a distantly evolved cousin of our native spider lilies, the genus Hymenocallis.
We typically don’t grow many non-hardy plants, but are interested to see if it will hybridize with our native Hymenocallis, since another Andean native, Ismene amancaes, has been successfully hybridized with Hymenocallis in the past. As this is a winter-flowering species, we have collected and refrigerated the pollen while we await Hymenocallis flowers.
Here’s our oldest specimen of xFatshedera ‘Curly’ in the garden this week. This fascinating bi-generic cross between the vining English Ivy (Hedera helix) and shrub Fatsia japonica ‘Moeseri’, was originally made 110 years ago this year, at France’s Lizé Frères Nursery. Since that time, we have been able to track down seven foliar mutations that have been named from the original hybrid.
Our specimen of xFatshedera ‘Curly’ has reached 6′ tall x 6′ wide in 10 years. The hybrid is no longer is capable of running like the ivy parent, but also has trouble looking exactly like a shrub. We enjoy it for its unique form, which is the anthesis of round green meatballs. .
xFatshedera ‘Pixie’ is a “dwarf” sport from F. ‘Curley’. Although the leaves are slightly smaller, the plant is actually larger. Our 10 year old specimen measures 6′ tall x 11′ wide this week.
Looking wonderful in the fall garden is the evergreen Choisya ‘Limo’, known commercially as Goldfingers choisya. This gold-leaved selection is from a cross of two Southwest US native shrubs, Choisya arizonica and Choisya ternata, subsequently referred to as Choisya x dewitteana. The genus Choisya is named to honor the late Swiss botanist/philosophy professor Jacques Denis Choisy (1799-1859) This gold-foliaged selection from the UK’s Peter Moore forms a 3′ tall shrub in 5 years.
The fragrant white clusters of axillary flowers adorn the plant starting in April (NC). We have our specimen planted in a full sun rock garden, where it thrives in very well-drained soils. Hardiness is Zone 6a-9b.
A couple of years ago, we made bi-generic crosses of the North American Manfreda maculosa and the naturally occurring hybrid Mexican tuberose, Polianthes x bundrantii ‘Mexican Firecracker’. These fascinating plants were still in full flower prior to our first hard freeze in the last few days. These are images of our top three clones, which we refer to as x Polifreda. Because we used the non-fragrant tuberose species, there is no noticeable aroma, but we opted for a much more diverse flower color range instead.
Hopefully, next year, we can use these to cross with agaves to create a new series of xHanseras. Pollen has been gathered and stored in the refrigerator in case bloom times don’t coincide next year.
We are always interested in checking out the offspring, when plants in the garden have unexpected romantic rendezvous with their distant cousins…often when we least expect it. We have found arums tend to be quite promiscuous in the garden. While most offspring go to the great compost pile in the sky, a few are worthy of adoption and naming.
Below is our selection of a cross of Arum dioscorides x Arum italicum that we named Arum ‘Love Child’. While the foliage resembles typical Arum italicum, the spring-borne flowers show great influence of Arum dioscorides with the purple spotting inside the spathe. It’s our hope that Plant Delights will have a first crop of this new hybrid to share in the 2023 catalog.
The shrubby North American native salvias including Salvia greggii and Salvia microphylla are spectacular plants in the fall garden. The same goes form the hybrids between the two species, known as Salvia x jamensis. Here is our clump of Salvia x jamensis ‘Blast’ looking absolutely stunning in late October. Flowering is heaviest in spring, slowing in summer, but again equaling it’s spring show in fall. Hardiness is Zone 7a-9b, and possibly a good bit colder.
Our 2016 century plant hybrid is looking quite lovely in the garden this month. This plant, which we named Agave x victorifolia ‘Prince of Whales’, is a hybrid of the Whale’s tongue century plant, Agave ovatifolia (male parent), and the Queen Victoria century plant, Agave victoriae-reginae (female parent).
Since both parents are non-offsetting, this means that the offspring will grow to maturity, flower, then die. Consequently, in order to be able to propagate and share, we will have to drill out the central core of the plant to trick in to offset. While this ruins the appearance of the original, it’s the only way for this to ever be shared and preserved. This plant has been in the ground since 2018, so we expect to have another eight years (guessing) prior to flowering. Consequently, so we’ll probably gamble on waiting a few more years before performing surgery. Winter hardiness is Zone 7b-10b.
Below is a photo of both parents.
Most folks are familiar with the mysterious Howard Hughes, but we have an equally mysterious “Howard” in horticulture. Flowering well now in the gardens at JLBG is the amazing xHowardara ‘Riley Kate’. This fascinating hybrid was created by Texas bulb guru, Dr. Dave Lehmiller, who crossed a Hippeastrum (amaryllis) and a Sprekelia (Aztec lily), and a Zephyranthes (rain lily). Lehmiller’s cross resulted in five different named cultivars and were subsequently named after the late Texas bulb guru, Dr. Thad Howard.
Creating a trigeneric hybrid is beyond rare, since it isn’t supposed to happen according to the rules of botany. Consequently, the introduction of the first clone sent taxonomists into a frenzy trying to publish new research to re-combine the genera involved into a single genus, so as not to have their rules violated. xHowardara’s occasionally flower for us in mid-summer, but peak flowering is always in September and October in our climate. Hardiness is Zone 7b – 9b, at least.
It’s not unusual for ferns to have sex in the wild, even with other species in the same genus. It is, however, unusual for them to have meaningful sex with ferns of an entirely different genus. Such an odd occurrence recently happened in the greenhouses of Louisiana’s James Georgusis.
One night, possibly after a wild Mardi Gras party, a willing Phlebodium got it on with a crested tongue fern of the genus Pyrrosia. The result was a new genus of fern, x Phlebosia. It was adopted and given the cultivar name, ‘Nicolas Diamond’. At least the parents had the good sense to sexually stay within the same family, Polypodiaceae
We planted our first specimens in the garden this February, and so far, it’s growing well. The key will be to see how much winter hardiness it has…fingers crossed. Both parents are pictured below the new hybrid.
Last year, we saw a listing for a new Mangave, M. ‘Purple Passion’ on the availability of a West Coast liner producer, so we ordered some to try. It was immediately evident when we unpacked the shipment, that the plants didn’t look anything like a mangave, nor did what we received match the image that the supplier had on their website.
As we dug deeper, we found that the supplier had misappropriated a mangave image from another wholesaler and was using it for the plant we purchased, desptie the two looking nothing alike. Once the image issue was remedied, we set out trying to track down the origin of this strange plant, which looked more like a steamrolled eucomis than a mangave.
The supplier sent us to their supposed source, who had never heard of the plant in question. For six months, we have chased down one lead after another, contacting all of the well-known plant breeders of these type of plants on the West Coast. All dead ends.
Examining the plant in our garden this summer, it occurred to us that the unusual leaf netting must have come from a beschorneria. Comparing the foliage netting of ‘Purple Passion’ to beschornerias in our garden yielded a perfect match, except for the leaf color. The only plant which could have been crossed with a beschorneria to give such leaf color is a manfreda. Hence, our conclusion that our plant is in fact a new bi-generic hybrid, x Beschfreda ‘Purple Passion’ (beschorneria x manfreda).
Since we don’t know which species of beschorneria was used, we are uncertain about potential winter hardiness, but with plants in the ground now, all we need to do is wait for cold weather. Below is a photo of the plant in the garden this week. If you happen to know more of the backstory of this fascinating plant, please let us know.
Here’s a new photo we just took in the garden that showcases the amazing architecture of xMangave ‘Falling Waters’ when it reaches maturity…pretty amazing!
Find out more about xMangave and their uses as a container specimen on FaceBook @MadAboutMangave.
The genus xmangave is an exotic botanical curiosity that was derived from a cross between an agave and a manfreda. Crosses between two genera are somewhat rare in cultivation and extremely rare in nature. However, agave and manfreda have broken all the rules and ‘hooked up’ on more than one occasion to produce the attractive offspring called x Mangave. The ‘x’ on the left side of Mangave tells you that it is a cross between different genera.

Both parents contribute drought-tolerance and an aversion to winter moisture. Keep your x Mangave roots dry in winter to prevent rot. We like them in containers. We have been busy making new x Mangave hybrids…so check back for updates!
